Definitions
- This invention relates to a fork positioner for moving the load-lifting forks of a lift truck carriage selectively toward or away from each other so as to change their transverse separation. More particularly, the invention relates to a fork positioner which can be attached to an existing lift truck carriage, or incorporated as original equipment in a newly-manufactured carriage.
- Fork positioners actuated by pairs of hydraulic cylinders, motor-driven screws, or the like have been used extensively on fork-supporting lift truck carriages. Most of these fork positioners are furnished as integral components of a carriage, often in combination with a side-shifting function which enables the carriage to be moved transversely so as to side-shift the forks in unison.
- Some detachably-mountable fork positioners have been provided in the past, such as those shown in U.S. Pat. Nos. 4,756,661, 4,902,190 and 6,672,823, to enable existing lift truck carriages without fork-positioning capability to be provided with such capability.
- FIG. 1 is a perspective view of an exemplary embodiment of a fork positioner in accordance with the present invention, shown prior to mounting on a load-lifting carriage.
- FIG. 2 is a front view of an exemplary load-lifting carriage mounting the fork positioner of FIG. 1 .
- FIG. 3 is a rear view of the carriage of FIG. 2 .
- FIG. 4 is a partially sectional side view of the carriage of FIG. 2 , taken along line 44 .
- FIG. 5 is an enlarged rear detail view of a center portion of the fork positioner of FIG. 1 showing interior hydraulic conduits.
- FIG. 6 is an enlarged rear detail view of a center portion of the fork positioner of FIG. 1 showing other interior hydraulic conduits.
- FIG. 7 is an enlarged rear detail view of a base portion of one of the piston and cylinder assemblies of the fork positioner of FIG. 1 .
- FIGS. 2-4 show an exemplary embodiment of a load-lifting carriage 10 mountable for vertical movement on the mast of an industrial lift truck (not shown).
- the carriage 10 can be any of numerous different types, usually having an upper transverse fork-supporting member such as 14 and a lower transverse member such as 16 mounting two or more load-lifting forks such as 18 by means of fork hooks 20 , 21 ( FIG. 4 ) slidably engaged for transverse movement by hook portions 14 a and 16 a , respectively, of upper member 14 and lower member 16 .
- the hook portions 14 a and 16 a may be integral parts of the upper member 14 and lower member 16 respectively if the carriage 10 is of a simple standard type.
- the hook portions 14 a and 16 a may be transversely movable relative to the remainder of the upper member 14 and lower member 16 on slide bushings such as 22 , 23 ( FIG. 4 ) under the control of a bidirectional side-shifting hydraulic piston and cylinder assembly 24 interacting between a side-shifting frame 25 containing the hook portions 14 a , 16 a , and the remainder of the carriage 10 .
- a side-shifting frame 25 enables the forks 18 to be moved transversely in unison if desired.
- the upper hook portion 14 a and lower hook portion 16 a of the carriage 10 are joined by respective end members 26 of the frame 25 which side-shift transversely in unison with the hook portions 14 a , 16 a and the forks 18 .
- end members 26 can join the upper member 14 and lower member 16 of a standard carriage.
- the carriage 10 is of the side-shifting type, its side-shifting piston and cylinder assembly 24 is preferably located immediately beneath, rather than above, the upper member 14 to maximize the operator's visibility over the top of the carriage when the carriage is lowered, and to leave an open space between the side-shifting piston and cylinder assembly 24 and the lower member 16 for enhanced operator visibility through the center of the carriage.
- the carriage 10 whether or not of the side-shifting type, be provided with a fork positioner for enabling the forks 18 to be selectively moved toward or away from each other so as to adjust the transverse spacing between them.
- a unique fork positioner indicated generally as 28 is disclosed in FIG. 1 .
- the fork positioner 28 may either be conveniently mounted to an existing carriage 10 having no fork-positioning capability or, alternatively, included as part of a carriage 10 as originally manufactured.
- the fork positioner 28 includes a pair of elongate, bidirectional hydraulic piston and cylinder assemblies 30 and 32 having respective longitudinal axes 30 a , 32 a ( FIG.
- a cylinder connector 34 is adapted to threadably interconnect the rod end portion 30 d of one cylinder rigidly to the rod end portion 32 d of the other cylinder so that the axes 30 a and 32 a are parallel to each other.
- a pair of fork-positioning guide members 36 , 38 each connects to a respective piston rod 30 e , 32 e by means of a respective rod connector 36 a , 38 a ( FIG. 3 ) while also slidably and guidably engaging the respective cylinder 32 b , 30 b of the opposite piston and cylinder assembly by a respective slide bushing 36 b , 38 b .
- This arrangement enables a recessed fork-engagement surface 36 c , 38 c ( FIG. 1 ) of each respective guide member to face away from the respective longitudinal axes 30 a , 32 a of the piston and cylinder assemblies in a forward direction substantially perpendicular to an imaginary plane 40 ( FIG.
- the plane 40 also interconnects the upper transverse member 14 and lower transverse member 16 since the piston and cylinder assemblies 30 and 32 are inserted between the members 14 and 16 .
- the piston and cylinder assemblies 30 and 32 can move the guide members 36 and 38 selectively toward and away from each other.
- Fork positioning force is applied by the guide members 36 , 38 to the sides of the respective forks 18 in a substantially direct, nonbinding fashion so that the forks slide easily toward and away from each other along the upper transverse fork-supporting member 14 .
- the fork-engaging surfaces 36 c , 38 c are preferably vertically coextensive with at least a major portion of the distance separating the respective longitudinal axes 30 , 32 a of the piston and cylinder assemblies.
- the piston and cylinder assemblies 30 and 32 are preferably mountable on the carriage 10 while interconnected with each other as a unit, for example by the cylinder connector 34 and/or the fork-positioning guide members 36 , 38 .
- This unitized insertable fork positioner package requires no unitizing framework other than the piston and cylinder assemblies themselves and, if desired, also the fork-positioning guide members.
- the resultant rigid, essentially frameless fork positioner unit is thus so compact that it can be mounted in its inserted position centrally on the carriage 10 without significantly impairing the operator's visibility, or altering the dimensions of the carriage 10 in a way that would push the load forwardly and thereby reduce the load-carrying capacity of the lift truck.
- mounting of the fork positioner on the carriage is greatly simplified by the unitized nature of the fork positioner, and by the fact that only the piston and cylinder assemblies 30 , 32 must be supportably connected to the carriage 10 since the fork-positioning guide members 36 , 38 are supportable by the piston and cylinder assemblies 30 , 32 independently of any engagement by either guide member with a fork 18 .
- piston and cylinder assemblies 30 and 32 One possible easy mounting arrangement for the piston and cylinder assemblies 30 and 32 is to connect the respective base portions 30 c , 32 c of the cylinders to respective end members 26 of the carriage 10 by screws 39 as shown in the drawings or by any other convenient means. If an existing carriage 10 has no such end members, they can easily be added to the carriage as part of the assembly process. Alternatively, the piston and cylinder assemblies 30 a , 32 a could be more centrally mounted to the carriage 10 by one or more brackets attached to the carriage upper member 14 or 14 a in a manner which does not significantly impair operator visibility through the center of the carriage.
- the cylinder connector 34 includes one or more hydraulic fluid line connectors 42 , 44 , 46 , 48 communicating with the interiors of the respective cylinders 30 b , 32 b .
- one such connector 44 FIG. 5
- another connector 42 FIG. 6
- Respective conventional flow equalizer valves such as 56 ( FIG. 7 ) in each base portion 30 c , 32 c achieve uniform movement of the piston rods.
- An operator control valve (not shown) can reverse the flows of pressurized fluid and exhaust fluid through connectors 42 and 44 respectively to similarly extend the piston rods.
- each cylinder 30 b , 32 b is connected to the carriage 10 so as to prevent the cylinder's longitudinal movement relative to the carriage
- a reversed structure wherein piston rods are connected to the carriage so that their cylinders can move the fork-positioning guide members would also be within the scope of the invention.
